A multiphase interleaved boost converter for grid-connected PV system

A multiphase interleaved boost converter with photovoltaic module using Maximum Power Point Tracking (MPPT) technique is the primary objective of this paper. Hence at the beginning, the PV module is analyzed in MATLAB using SIMULINK software. In this project, simulation& design of a close loop three phase inverter in MATLAB SIMULINK platform is also presented. That is also a part of PV grid connected systems. There are many MPPT methods given by the researchers. Among them P&O method and INC method are mostly used. Here P&O algorithm is used because of its advantages over INC method. P&O MPPT algorithm having faster dynamic response and well-regulated PV output voltage than hill climbing algorithm.
